A'PEXi N1 Cat-Back Exhaust 2G AWD DSM

A'PEXi's N1 series is patterened after the systems used on the N1 endurance race cars in Japan. They include ceramic-coated mild steel piping with a full 3" diameter, expanding to a whopping 3.3" at the back end. The tip is 4.5" in diameter.

Each system comes with a bolt-in silencer you can insert when you want to be discreet; it fits inside the tip, reducing the opening to 2" and dampening the sound. With the silencer out, the sound is a fairly loud, but pleasant and deep, growl.

The built-in reducer adapter on the front of the system is another nice feature. With the adapter on, it'll bolt straight to your stock cat. With it removed, you have a straight 3" pipe that can bolt to an A'PEXi race downpipe or any other 3" pipe you want to fabricate, for a complete un-restricted 3" system.
